[hp pavilion ze4222] cd writer issue

[ale <aleqivu@yahoo.it>]

Hi everybody,
I'm new to the list and relatively new to debian. I'd been using some 
debian based distros (knoppix, kanotix, mepis, dsl) for some time and 
now, finally, I switched to Debian Sarge (kernel 2.6.8-1) thanks to its 
fantastic net installer.

BUT...

now I have some problems that I had never experienced with other distros.

First off the cd writer (others will come...)

My cd-rw doesn't work, it can only read cds (with other distros it 
worked fine save for cleaning cdrw...). I don't understand what the 
problem is and I don't know where to start from to find a solution, so 
here I am!

During boot the machine finely detects my cd writer/dvdrom:
hdc QSI CD-RW/DVD SBW-241 ATAPI CD/DVD-ROM DRIVE
but then it only works as reader. I tried cdrecord -scanbus and this is 
what I got:

# cdrecord -scanbus

cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open

cdrecord: For possible targets try 'cdrecord -scanbus'.

cdrecord: For more information, install the cdrtools-doc
cdrecord: package and read /usr/share/doc/cdrecord/README.ATAPI.setup .

Then:

I edited my /etc/default/cdrecord like this (only relevant lines):
CDR_DEVICE=cdrw
# drive name    device    speed    fifosize driveropts
#
teac=        1,3,0    -1    -1    ""

cdrom=        0,6,0    2    1m    ""
cdrw=        1,0,0    12    30m

What can I do?

Thanks,
Ale.
